A tool like Fritzing might be helpful. It's not a simulator, though.

There's a lot of 555 projects tagged. I'd look for other similar projects that don't "float" pins 4 and 7. Unconnected, those are undefined and your project might not work as planned (stuff like parasitic capacitance will effect the build, and won't be the same on a PCB as on a breadboard...).

A simple simulator like CircuitLab would help dial in your project.

If it's working as intended then what's the issue? You don't have to use every pin on the timer to make a functioning circuit.

What are you basing it on? If it works, it works.
